Subtract 21 from 70 to get 49.

$$\sqrt{\frac{6}{25}\left(\frac{\frac{49}{4}}{\frac{49}{30}}-\frac{3}{2}\right)}$$

Divide \frac{49}{4} by \frac{49}{30} by multiplying \frac{49}{4} by the reciprocal of \frac{49}{30}.

$$\sqrt{\frac{6}{25}\left(\frac{49}{4}\times \frac{30}{49}-\frac{3}{2}\right)}$$

Multiply \frac{49}{4} times \frac{30}{49} by multiplying numerator times numerator and denominator times denominator.

$$\sqrt{\frac{6}{25}\left(\frac{49\times 30}{4\times 49}-\frac{3}{2}\right)}$$
